Abstract

The invention discloses an adsorption material based on antimony tailings and its preparation method and application. The material is prepared from the following composition in mass percentage: 50%-90% of antimony tailings, 50%-10% of viscous agent; the material After the adsorption performance test, the results show that the material has high adsorption performance for high-concentration organic emulsified wastewater and heavy metal-containing wastewater, and has relatively stable chemical properties, developed pores, high mechanical strength, and high temperature resistance. It has broad prospects in the field of chemical utilization and adsorption materials.

Description

technical field [0001] The invention belongs to the field of environmental functional materials, and in particular relates to a preparation method and application of an antimony tailings-based adsorption material. Background technique [0002] my country's antimony reserves and production are the first in the world. In recent years, my country's antimony production accounts for about 90% of the world's total. Due to the large-scale development of antimony mines, a large number of antimony pollution accidents and relatively serious antimony pollution problems have been caused, especially In Guangxi, Hunan, Yunnan, Guizhou and other southern provinces where antimony mines are relatively concentrated, there is a large amount of antimony tailings accumulation, so the whereabouts of antimony tailings has become one of the hottest topics in tailings treatment today. [0003] In 2016, CN201610031832.9 disclosed a kind of antimony tailings slag aerated concrete block and its preparat...
